Frederiksted, Virgin Islands (U.S.): Submarine Cable Landing Point

Frederiksted is a town on the western coast of St. Croix, the largest of the U.S. Virgin Islands by land area. Situated on the leeward side of the island, Frederiksted's naturally deep coastal waters have historically made it accessible to maritime traffic. One submarine cable lands at Frederiksted, connecting it to the broader inter-island telecommunications infrastructure of the U.S. Virgin Islands.

The single cable landing here, the St. Thomas-St. Croix System, operates entirely within U.S. Virgin Islands territory, linking two of the territory's main islands. This makes Frederiksted a domestic inter-island cable terminus rather than an intercontinental or international gateway. Its cable corridor is intra-territorial, supporting connectivity between St. Croix and St. Thomas.

Cables Landing at Frederiksted, Virgin Islands (U.S.)

The St. Thomas-St. Croix System is the sole submarine cable landing at Frederiksted. Spanning approximately 183 kilometers, it reached ready-for-service (RFS) status in 1997, making it among the earliest submarine cable deployments in the U.S. Virgin Islands. Both endpoints of this cable fall within U.S. Virgin Islands territory, reflecting its role as an intra-territorial link between St. Croix and St. Thomas. The cable's draft status indicates it may carry provisional details in available records.

Regional Context

Within the U.S. Virgin Islands, which hosts seven submarine cables distributed across nine landing points, Frederiksted serves as a single-cable landing site — a category it shares with Banana Bay, Brewer's Bay, Christiansted, and Flamingo Bay. The most connected landing point in the territory is St. Croix, Virgin Islands, with five cables, followed by Great Bay with two. Frederiksted's position among these peers places it in the mid-to-lower range of the territory's cable infrastructure by cable count, though it remains one of the few points on St. Croix's western coast with a submarine cable presence.

Network Role

Frederiksted functions as a single-cable terminus within the U.S. Virgin Islands' intra-territorial submarine cable network. The St. Thomas-St. Croix System, landing here since 1997, enables direct undersea connectivity between St. Croix and St. Thomas, supporting the inter-island communications link that predates several other cable deployments in the territory. As a domestic-only cable endpoint, Frederiksted does not participate in international or intercontinental routing through this cable.

In the broader submarine cable geography of the U.S. Virgin Islands, Frederiksted represents one of several distributed landing points on and around St. Croix, each contributing to the island's overall connectivity. Its place in the regional cable graph is that of a single-link node connecting St. Croix's western coast to the principal island of St. Thomas.
